My deer hunting started at age 16 in 1960, so I experienced the same things talked about above.
Posted signs were something that the small family farms never wasted time putting up. The farmers back then were happy to see hunters thinning the crop-scavenging deer. Trespass was an unheard-of word. Begging for permission to hunt land was also unheard of. You could still hunt as far as your legs would carry you without ever seeing a sign.
Opening day of deer season was a forgiven absence from school and pretty much expected. Hunter safety classes were held in the school bus garage on school property.....With actual guns .... Imagine that!
There were no how-to-do-it videos, and only magazine articles if you happened to be a kid with enough cash to subscribe to them. How on earth did we ever get a deer? Tree-stands?.... Only 2 x 4's nailed into trees but more likely just some dead logs and brush dragged up into a ground blind. Fred Bear wrote about those in the archery magazines.
Camouflage??? That was for use in wars, not deer hunting. Some old red and black checkered coat was what identified you as a hunter and not a deer. Bow hunting was done in blue jeans and whatever shirt or coat you had available. State parking lots were filled to overflowing. Cars and trucks lined the roads. Farmer's driveways were filled with cars.
Antler scoring ..... I guess the systems might have been around back then, but I never heard of such nonsense until more recent years.
Food plots to condition the deer to come to your gun or bow. Who the heck ever did that?
Hunting was a whole lot different than today with all our new-fangled things that you HAVE to do and own to get a deer. And yet somehow we did actually get some deer. Yeah, there were a lot of times when we didn't. But hunting was more about the pursuing than the harvest. The kill was the bonus that came on top of the hunt. And you know what, with all these primitive deer-getting rules and gotta-haves, hunting was a lot more fun and there was no worrying about recruiting the next generation of hunters. That simply was the nature of humans back then, not something that you had to bribe kids with by creating special seasons. We all waited in anticipation for the proper age when we were allowed to hunt.
Very different world back then. Oh, and by the way, something else we didn't have back then was locks on our doors.
